• Edge Case 1 - Specific instructions related to combination products
• Edge Case 2 - Defining a maximum dose per course
• Edge Case 3 - Defining a period of time where medication should not be taken
• Edge Case 4 - Medication request instructions including use of a specific device
• Edge Case 5 - Defining a Trade Family without using an AMP
